Loops and Sequences
Students learn to repeat actions efficiently using loop blocks (forever, repeat, repeat until) and understand how the order of blocks in a sequence changes the program's behaviour.

Broadcast and Wait

broadcast (message) and wait sends the message AND pauses the sending sprite’s script until all receivers have finished running their “When I receive” scripts.

When to Use It

Use “broadcast and wait” when the next step must happen AFTER the receivers finish. For example:

  1. Broadcast (show intro animation) and wait — pauses game setup.
  2. After the animation finishes, the game setup continues automatically.

Plain broadcast vs. broadcast and wait

Plain broadcast: sender continues immediately. Broadcast and wait: sender pauses until all receivers finish.
